OVERVIEW
The CashFlow 560 range of changegivers have been designed to
address a wide range of market needs and are compatible with the
majority of modern vending machines. They are plug compatible
replacements for the previous MS1600, ME1600 and ME1900
series of changegivers. The flexible approach allows easy matching
of modules for all types of applications. They are designed to work
with a wide range of coinsets and can be upgraded to accept new
coins. There are four change tubes and field selection of the coins
to be stored in them is possible. On the front of the changegiver is a
keypad which is used to dispense coins and re-configure some
aspects of the changer. All CashFlow
560 changegivers are made
up of several modules;
• Control board
• Spine
• Transformer
• Keypad
• Dispenser
• Acceptor
• Separator
• Coin Storage Cassette

PRODUCT OPERATION
GENERAL
ELECTRO-MECHANICAL PRODUCT
When a coin is entered through the electro-mechanical changegiver
there are several conditions that are electronically checked.
After coins have been accepted and a product selection button is
pressed a sense current flows through the changegivers sense
circuit. The sense current is not sufficient to energise the relay, but
enough for the changegiver to detect. When the changegiver
detects that a product selection button has been pressed the
changegiver looks up the price associated with the selection. If
sufficient credit exists the changegiver turns the price line output on.
This disconnects the safety line from price line common and
connects the price line output to price line common. The vend motor
relay within the vending machine is then energised, turning the vend
motor on and closing a switch across the selection button.
When the vend cycle begins the blocker signal indicates to the
changegiver that a vend has started. The price of the vend is
deducted and the changegiver waits for the vend to finish. The price
line output is turned off when the changegiver considers the vend to
have finished.
Unused credit may be returned after the vend has finished either
automatically if in single vend mode, or by customer demand if it is
in multi vend mode, or after a pre-determined time in multi-vend
option setting, depending on how the changegiver has been set up.
SERIAL INTERFACE PRODUCTS
Dependent on which version of product is being used , when coins
or cashless card are inserted the value involved will be shown on the
display, if used. The host machine’s VMC communicates all
functions as required with the changegiver and any other
peripherals, such as an audit unit or cashless payment system, that
are being used.
The VMC in the host machine produces signals to the changegiver
(excluding MDB product) indicating when a vend is to be made, and
the value of the vend required. The changegiver will then ascertain
if sufficient credit is available to cover the cost of the vend. If the
changegiver is set to “No Overpay” it will confirm that any remaining
coin credit that would result from the vend can be returned before
authorising the vend.
Page 12
6©, MEI., 1996.
CashFlow 560 changegiver Applications Design Guide
If the vend is allowed the cost will be deducted from the credit prior
to authorising the VMC to start the vend. Should the vend fail, this
credit will be re-instated.
ACCEPTOR MODULE
There are some functions of the acceptor module which are
common across the whole CashFlow
product range. These
include coin discrimination, control and communication.
When a coin is put through the acceptor module it’s validity is
determined by measuring certain parameters. It also looks at the
coin type status to define whether the payment is a valid coin or
token, or an invalid coin. Finally, the inhibit status is checked. If the
coin is not inhibited, then it will be accepted, the accept gate
opened, and the coin routed to either a tube or cashbox. The
acceptor module is made up of the discriminator, back cover and the
accept gate.
The discriminator comprises a flight deck and lid which together
form the coin control and flight path. On the inside of the flight deck
lid there is a mechanical device incorporated near the coin entry
point. This device is known as the coin deflector and is used to bring
coins under control as they enter the product
Acceptor Module
A hinge at the top right hand side of the flight deck allows coupling
of the lid via an intermediate component, known as the lid arm. This
allows the lid to locate accurately to the flight deck independently of
the hinge. The lid also maintains a parallel coin throat by being

spaced from the deck on three bosses which locate the lid squarely
to the deck.
The design of the lid arm hinge area allows the lid to open to 180
degrees relative to the deck. The opening is restricted to just over
100 degrees by the back cover to prevent the lid possibly fouling
other parts.
The action of the hinge spring allows the lid to remain open when
past about 100 deg. and will snap shut when closed to about 60
degrees although the lid will need to be pressed to ensure that it is
correctly seated against the deck. The acceptor module connects to
the control board via a 10 way ribbon cable.
On the front of the acceptor module there is a six way socket. This
is for use with a MEI
Route Alpha 250 terminal. The terminal is
hand held and, when connected to the acceptor, allows some of the
operational aspects of the changegiver to be altered.
ACCEPT GATE MODULE
The accept gate module contains a solenoid operated gate, optical
coin strobes and coin routing components. Coins that are correctly
discriminated are routed to the accept exit by energising the accept
gate. Coins that are rejected are routed to the reject exit.
SEPARATOR
The separator separates the coins into different routes, either to the
coin storage tubes or the cashbox. It contains a solenoid bank and,
at the bottom, a top level sensor assembly which is used to avoid
tube overflow.
CONTROL BOARD
This is the main PCB which controls the way in which the
changegiver operates. There are several different control boards,
but basically these are the 4 price for electromechanical machines,
and the Executive, MDB and BDV for electronic machines.
SPINE
The spine provides the housing for all of the other modules. On the
rear of the spine are the three standard keyhole fixing points for
fitting the changegiver into a machine.
Page 14

CashFlow 560 changegiver Applications Design Guide
TRANSFORMER ASSEMBLY
The transformer assembly is housed behind the keypad cover. To
gain access to the transformer there is a screw located under the top
flap of the keypad cover. Once this screw has been removed the
keypad cover will lift off and the transformer is accessible. The
transformer connects to the control board via two looms and is
available in 24V, 100V, 120V, 220V, and 240V options.
Note: On CashFlow
560 BDV and MDB changegivers the
transformer is replaced by a reservoir capacitor.
KEYPAD
The keypad is used to float or dispense coins and to re-configure
some aspects of the way in which the changegiver works.
DISPENSER
The dispenser is held in the spine by two clips, one on each side. It
connects to the control board via a loom. It contains four dispense
arms which, when operational, dispense coins from each of the four
storage tubes. The dispenser also contains low level sensors which
detect when the coin tubes are low on coins. It is possible to
dispense coins from more than one tube at the same time.
COIN STORAGE CASSETTE
The coin storage cassette clips to the front of the changegiver and
contains four independent coin storage tubes. There are thirteen
different sizes of tube, each numbered from 0 - 7. These cover most
sizes of coins that you should want to route to coin tubes.
N.B. Some have a suffix of “.5” (i.e. 2.5), and dimensions range from
0 which has the largest bore and 7 with the smallest bore. Each tube
has a designator fitted at the bottom. The size of the designator
fitted is dependant upon the thickness of the coin. There are eight
different sizes of designator each lettered from A - H.
The front cover is marked A,B,C,D to indicate the position of the
fitted tube, as shown below. Coins of the following sizes can fit into
each of the positions:
• Coin diameters from 15.0 to 26.0 mm in position A
• Coin diameters from 18.6 to 32.5 mm in position B
• Coin diameters from 15.0 to 29.2 mm in position C
• Coin diameters from 18.6 to 29.2 mm in position D

CashFlow 560 changegiver Applications Design Guide
Although there are different sizes of tubes and designators
available, not every tube can be fitted into every position in the
cassette.
There are prisms located at the top of each tube which, when
combined with the optos on the separator form the top level sensor.
The top level sensors are used to indicate when a tube is full. When
a tube is full any further coins are routed to the cashbox.
The cassette can be automatically filled by feeding coins through
the product, or manually filled by removing the cassette from the
changegiver.
On the front of the cassette are float indicators which you can
position manually by sliding up and down.
Exact Change Equation
When the changegiver, other than MDB product, detects that the
quantity of coins in a coin tube is below the low-level sensor, a
signal is sent to the vending machine to switch on the exact change
light (ECL) so as not to risk short-changing a customer.
Setting the exact change equation ensures that the optimum
combinations of change coins are always dispensed, by using
coins from alternative tubes to make up the change required, and
that the ECL is on for the minimum time possible.
An explanation of the process used to determine the optimum coins
for change can be found later under the heading of Best Change
Calculation.
Two exact change equations can be set using Route Alpha 250
terminal, addresses 236 and 237. The tubes A, B, C and D are
coded 1, 2, 4 and 8
Address 236 = exact change equation, part 1 - offers the first option
to use change coins from nominated tubes .

Address 237 = exact change equation, part 2 - sets a second
selection of change tubes.
Address 383 can also be used, with BDV product only, to give an
additional early warning setting, (in conjunction with addresses
271-274), and trigger the ECL to come on at an earlier point when
the coin count in a selected tube becomes low coded 1, 2, 4, and 8.
EXAMPLE: A four-tube changegiver contains 1p, 2p, 5p and 10p
coins, and the vend price is 16p.
If 20p is inserted, the optimum change payout will be from tubes A
and B. Therefore address 236 - exact change equation, part 1must be set to 3 (using code 1 + code 2 to equal 3). This setting will
ensure that the ECL comes on when tubes A and B become low.
If 50p is inserted, the optimum change payout will be from tubes A,
B AND D. Thus address 237 - exact change, equation part 2- must
be set to 11( using codes 1 + 2 + 8 to equal 11. This setting will
ensure that the ECL comes on when tubes A, B and C become low.
Setting both addresses 236 and 237 will cause the ECL to come on
when tubes A and B, or tubes A, B and C become low.
If the vending machine becomes inhibited (blocked) this is signalled
to the changegiver by the blocker signal. During the inhibited state,
coin acceptance is disabled. This condition may occur because
there are no products left in the machine, or the machine has
developed a fault.

Using Exact Change Inhibit
When the machine is in exact change mode, selected coins can be
inhibited, other than with MDB product.
Setting the exact change inhibit option will stop a specified coin or
coins being accepted when the exact change light is on. It is usual
to inhibit the highest value coin(s) to minimise the risk of the
customer being short-changed.
When the coin level rises again above the low count, the ECL is
turned off, and the inhibit option switched off so that the previously
inhibited coins are accepted.
The coin set for the unit is divided into three exact change groups,
in which each coin has a code. The groups are associated with
addresses 232, 233 or 234. Set the range value of the addresses to
the code of the coin you want to inhibit. Add the codes together to
inhibit more than one coin at a time in each group.
Addresses 232 - coins 1 - 4 using codes 1, 2, 4 and 8
Addresses 233 - coins 5 - 8 using codes 1, 2, 4 and 8
Addresses 234 - coins 9 - 12 using codes 1, 2, 4 and 8

CashFlow 560 changegiver Applications Design Guide
COIN ACCEPTANCE, ROUTING & RETURN
The changegiver has a standard coin entry and exit chuting. Coin
return via a reject lever is also standard. The coin acceptance, and
the routing used on coin acceptance, are dependant on:
• The set up of various configuration items in the
changegiver EEPROM
• Other changegiver conditions which will alter while the
changegiver is in operation
As a result of this, both coin acceptance and coin routing are
dynamic, i.e. changing in time as the state of the changegiver alters.
The dependencies are detailed in the following sections.
COIN ACCEPTANCE
The acceptance of each coin is determined primarily by the set up
of default inhibits in the EEPROM. This specifies which coins should
always be inhibited (i.e. rejected). In addition to these defaults, extra
inhibits will be imposed depending on the following conditions:
In normal mode with the overpay inhibit flag set:
• Coins which are not dynamically routed to the tubes will
be inhibited and rejected if their value, plus the existing
coin credit, cannot be returned due to lack of correct
change coins
• Coins which would take the total system credit over the
maximum allowed credit are inhibited
• Vend tokens are inhibited if the total system credit is
not zero
In normal mode with the overpay inhibit flag clear:
The Vending Machine Contoller (VMC) overules this in the MDB
product
• If use exact change has been signalled, the exact
change inhibits are imposed
• Coins which would take the total system credit over the
maximum allowed credit are inhibited
• Vend tokens are inhibited if the total system credit is
not zero
In float mode:
• All coins which are not dynamically routed to the tubes
will be inhibited
In price teach mode:
• Coins which would take the total system credit over the
maximum allowed credit are inhibited
• Vend tokens are inhibited

CashFlow 560 changegiver Applications Design Guide
Global Coin Inhibit
In addition to the individual coin inhibits described above, a global
coin inhibit can be imposed. This will inhibit all coin acceptance
regardless of any other conditions. A global inhibit is imposed when:
•Manually dispensing coins either from the key pad or
the terminal
•Returning credit
•A vend is in progress (VMC function on MDB)
•A price is on the display due to a product selection
being made with insufficient credit. (When in price
display mode). (Not on MDB)
•Value of tube contents is on the display. (Not MDB)
•Any bits in the EEPROM error register are set, apart
from code 5
•A free vend token has been accepted
•An executive type vending machine has indicated that
it requires a free vend
•The host machine has indicated it is inhibited
•The cashbox error code or if the protocol A error code
is set
•The blocker signal is not present
COIN ROUTING
The coin routing used is determined in the EEPROM. If a tube is not
fitted this is indicated as 00 on the MEI
®
Route Alpha 250 terminal
display. In addition, there are conditions which prevent coin routing
to a tube even when it does store the coin. These are any of the
following:
• The tube full sensor reads covered (or has failed its
self-test, if test enabled on acceptor)
• There was a fatal dispenser error on that tube
• The tube counts held in changegiver RAM are equal
to, or greater than, the maximum level for that tube.
The routes, determined by all the above criteria, are the dynamic
routes. Before a coin can be routed it must first be accepted. If a coin
is rejected none of the above applies.

CashFlow 560 changegiver Applications Design Guide
CHANGE PAYBACK
In general the changegiver will attempt to return any coin credit to
the consumer, in the best possible coin mix. However, this simple
statement requires clarification.
Use of Tubes
• The changegiver will only attempt to use tubes which
are shown as fitted, and have not been disabled by the
occurrence of sensor or dispenser faults
• If a tube is fitted and is not disabled, it will be allowed to
be used for change payback only if its tube counts are
above the safe count value at the start of the change
payback sequence
• The changegiver will not function if the coin storage
cassette is not fitted
Best Change Calculation
Once the tubes that can be used have been determined the best
coin mix to pay back the change is calculated. Best coin mix is
defined as the first of the following found to be possible:
• Correct change paid with minimum number of coins
• Correct change paid with non-optimal coin mix
• Closest change paid with minimum number of coins
• Closest change paid with non-optimal coin mix
• No change paid
Once the best coin mix has been determined the dispensers will
start to pay the change out. The software will drive as many motors
as possible at once to expedite the change payback. (Not MDB)
Should either of the following occur the dispense sequence will be
suspended once each motor has got to its home position:
• The tube has run out of coins while coins are still
required. This could occur if the low level sensor/s go
from covered to uncovered, causing a tube count
recalibration, which reduced the number of coins held
in the tube. (Not MDB)
• A dispenser error is detected (stall, etc.)
The software will then re-compute the best coin mix to pay back the
credit still remaining and re-start the dispensers with this new coin
mix. The above will be repeated until all the change which can be
dispensed has been paid.

CashFlow 560 changegiver Applications Design Guide
TUBE SENSOR USAGE
This section describes the operation of the tube sensors in more
detail. The sensor operation significantly affects the users
perception of how the changegiver appears to operate.
Each tube has associated with it three sensors:
• The full level sensor (opto sensor)
• The low level sensor (opto sensor)
• The tube dispenser home position sensor (reed switch)
Full sensors
Effect on coin routing
The changegiver cannot read the tube full sensors directly, but must
request their status from the acceptor module. The acceptor module
then performs a self-test of the full sensors. The acceptor module
reports both the reading of the sensor, covered or uncovered, and
the outcome of the self-test, OK or failed.
The changegiver will perform the following actions, on a tube-bytube basis, based on the self-test results and the sensor reading:
Self-Test
Result
Sensor
Reading
Changegiver Action
OK Un-covered
This is the normally expected
result. The changegiver will clear a
full sensor error, if flagged. It does
not take any further direct action.
However the routes may be
updated if the tube counts have got
to their maximum level
OK Covered
This is a fault condition, as the
maximum level a tube should reach
is 3 coins from full. The
changegiver will signal a full level
sensor error. If the low level sensor
is reading covered then there is a
good chance that the tube is really
full, so the changegiver will
recalibrate the tube counts to the
pre-programmed Full Number.
Page 23
©, MEI., 1996.17
CashFlow 560 changegiver Applications Design Guide
Coin cassette removal detection
If the coin storage cassette is removed, all the tube full sensors on
the tubes will read covered. Should the changegiver detect this all
tubes full condition, it will flag a cassette removed error and will
indicate a changegiver error on the error LED. No change payback
will be attempted from the tubes. Manual dispensing from the tubes
will still be allowed, but the tube counts will not be decremented.
Coins will still be accepted but routed to the cashbox.
The error will be cleared as soon as a coin is accepted or a dispense
Failed Un-covered
This condition cannot occur, as the
acceptor will always assume any
failed sensors are covered, and will
act as if this is so.
Failed Covered
This is a fault condition, due to the
failure of the acceptor module’s
sensor self-test (opto was seen on
with the LED being off). The
changegiver will signal a full level
sensor error. It will ignore the
reported reading, and continue to
use the last (good) reading before
the failure. The routing will be
updated. The tube is still used for
dispense. If all 4 main tube sensors
are reported as failed, then the
cassette is assume to be removed,
and a cassette out error will be
flagged.
Note that sunlight, or other intense
light source can affect the sensor
self-test, causing it to fail. Thus the
changegiver will inhibit the self-test
feature when float or price teach
mode is entered. When this mode
of operation is selected, the selftest result will always be OK.

attempted with the coin cassette back in place. Note that if all tubes
really have overfilled to cover the sensors then a cassette removed
error will be indicated, but will clear once the tube level drops.
Full sensor error detection
The changegiver will detect full sensor errors on dispensing from a
tube if coin storage cassette removal has not been detected. The
appropriate full sensor error register will be set and a changegiver
error will be indicated on the error LED. Since the sensor reads full
the tube will no longer be routed to, but no other action will be taken,
i.e. the tube will still be dispensed from.
The full sensors are read on initialisation, acceptance and
dispensing coins. Full sensor errors relating to a tube are cleared
whenever a full sensor reads uncovered. Note that this means that
if more than 1 coin covers the full sensor, the full error for that tube
will initially be set on dispensing from that tube, but it will be cleared
again as soon as the sensor becomes uncovered.
Coin count re-calibration
When accepting coins, the full sensors will be used for re-calibrating
the number of coins in the tubes. For any given coin type the number
of coins that it takes to cover the full sensor can vary due to
variations in coin thickness. For this reason the tube counts for a
tube will be set to be their full re-calibration number only if:
• The sensor status has changed
• The result of the sensor self test was good
• A coin cassette error has not been detected
• The recorded tube counts are more than 9 from their
expected level:
Low sensor error detection
The low sensor is checked at the following times:
• On power-up
• Before beginning any dispensing, either manual
dispensing or credit return
• Immediately after every coin is paid out
• One second after a coin is accepted
The status of the low level sensors will be held in non-volatile
memory, thus preserving this information for the next power-up.
Page 25

CashFlow 560 changegiver Applications Design Guide
Coin count re-calibration
Low level recalibration is intelligent in its handling of tube storage
cassette removal and replacement. The main assumption made is
that the tube storage cassette is not removed during a change return
operation. The following table gives the details of the low sensor
operation.
A tolerance of +/-one coin is applied to the tube counts before
recalibration on low level sensors is done. This reflects the fact that
due to the variables, both electrical and mechanical, it is unlikely that
the number of coins in a tube will always be the same.
Thus, if the tube counts are within one of their expected level , no
recalibration will occur when the low sensor goes from covered to
uncovered.
Page 26
20©, MEI., 1996.
CashFlow 560 changegiver Applications Design Guide
The following table gives a brief summary of the low sensor
operation.
Home sensors
The function of the home sensors is to signal that the dispenser
arms are in the correct parked position before an attempt to
dispense coins from the coin storage cassette is made. Should this
fault have occured then an error signal will appear on the (red) error
LED on the keypad, which will flash on and off.
To remedy this the coin storage cassette should be removed and
then pressing the (yellow) mode key twice. This will drive the
dispense arm solenoids and and all 4 of the dispense arms will be
parked in the correct position in sequence.

ELECTRO MECHANICAL INTERFACE
All electro-mechanical interface connections between the
changegiver and the host vending machine are electrically isolated.
Outputs are isolated via the relays (i.e. price line outputs) and the
inputs from the machine are current limited and optically isolated.
The standard electro-mechanical interface parameters for all
changegivers defined in this specification are as follows:
EXACT CHANGE OUTPUT
(Switched neutral). Rated 0.5 Amps AC resistive load. Fused 1.6
Amps thermal. Fault rating 3.5 Amps.
When the changegiver detects the change available in the tubes is
low it indicates exact change to the vending machine. The machine
normally uses this signal to illuminate a lamp informing the customer
to use the correct money.
CREDIT RELAY DRIVE
(Switched Ground). Open collector drive provided (includes flyback
diode) - 20mA @12V.
The credit relay is only available on the 4 price changegiver as an
option located outside the unit.
SAFETY LINE
(Switched Price Line Common). Rated 2.6 Amps. Fused (via price
line common) 3.15 Amps fast. Fault rating 7.0 Amps.
This output is normally connected to price line common via all the
price line relays (in their off state). When any price line becomes
active the safety line becomes open circuit within the changegiver.
PRICE LINE COMMON
(Normally connected to Line). Rated 2.6 Amps AC inductive load.
Fused 3.15 Amps fast. Fault rating 7.0 Amps.
PRICE LINE OUTPUTS
Rated 2.6 Amps AC inductive load (worst case power factor of 0.5).
Fused (via Price Line Common) 3.15 Amps fast. Fault rating 7.0
Amps.
A sense input will be seen when >1.5mA is flowing through the
sense input. When a sense input becomes active the changegiver
determines the price to be charged for the selection requested. If
sufficient credit exists it will energise the appropriate price line relay.
This relay will disconnect Safety from price line common and
connect price line common to the selected price line output enabling
the vending machine to proceed with the vend cycle.
Page 32
26©, MEI., 1996.
CashFlow 560 changegiver Applications Design Guide
MACHINE INTERFACE
The normal idle state of the Electro-mechanical / 4 Price machine
interface with no credit is as follows:
• Blocker input active (connected to LINE)
• EA input (if present) - inactive
• Sense input lines inactive (open circuit)
• Safety Line output connected to price line common (via
ALL price line relays)
• Price line outputs inactive (open circuit)
• Credit relay off (contacts open) - when optional box
fitted
• Exact change output inactive (contacts open)
The 4 price changegiver has 4 input/output lines, providing for 4
sense inputs, and 4 price line outputs. When a product selection is
detected the appropriate price line output is enabled (if sufficient
credit exists). As the price line relay outputs are interlocked,
enabling one price line output ensures that the other price line
outputs are disabled. When the reset condition is detected the price
relay is turned off.

SINGLE / MULTI VEND
Unused credit (change) is returned to the customer either
automatically or on demand by pressing the reject lever. If the
changegiver is set to single vend mode any unused credit is
returned automatically immediately after the vend finished condition
is met. In multi vend mode the credit balance is not returned until
requested by the customer (or automatically after a selectable
timeout period has elapsed).
SENSE INPUT TIMING
During the period between pressing the product selection button
and the price line output becoming active the changegiver must
determine the price line of the selection, look-up the vend price and
decide whether to allow the vend, and if so energise the price line
relay. If the sense input from the vending machine is A.C. the sense
current is only detected during the positive half cycle, therefore it
may be 1/2 cycle (i.e. 10mS) before the sense input is detected,
leaving 25mS for everything else.
VEND START
When a price line output has been energised the changegiver will
wait for the vend start signal. This is indicated by the blocker input
becoming inactive. If the vend start signal is not seen within 2.5 +/-
0.5 seconds of the price line output being energised the price line

output is removed (excluding blocker hold reset mode). The price
line output will be energised again if the sense input is still active and
sufficient funds exist to pay for the product requested.
VEND FINISHED
While the vend is in progress the vending machine holds the blocker
signal inactive. When the vend is finished the blocker signal returns
to its normal active state. As far as the changegiver is concerned the
vend is considered to have finished when the reset conditions are
met, and the price line output is disabled. The changegiver can be
programmed to several different reset conditions to suit different
vending machine interfaces:
• Blocker reset
• Delayed blocker reset
• Blocker hold reset
• Escrow accept reset
If the reset conditions are not met (i.e. the vend failed), the vend
price will be paid back to the customers credit balance.
BLOCKER RESET
The changegiver assumes the vend has finished successfully as
soon as the vend start signal is received (blocker signal is seen to
be inactive). The price line output is turned off at this point, with no
added delay. This is typically <30 mS.

DELAYED BLOCKER RESET
Blocker reset is the most commonly used reset condition
In this reset mode the price line output remains active for either 30
mS (most commonly used) or 200 +/- 10 mS after the vend start
signal is detected (blocker signal removed). The vend is assumed to
have finished successfully after this delay and the price line output
is turned off. The product may be in either 30mS or 200mS mode.
The delay is required to ensure the price line output is active for
sufficient time for some machines to latch the signal.

ESCROW ACCEPT
In this mode the escrow accept (EA) input is used in conjunction with
the blocker input to indicate a successful completion of a vend cycle.
Normally, blocker removal signals the vend has started. The end of
the vend is indicated when EA becomes active while blocker is still
inactive. If the blocker signal returns to its active state before EA is
active the vend is deemed to have failed, the price output is deactivated and price of the vend is added back to the credit so that
the customer can try again or have his money back.
To allow for any fault condition the changegiver will only wait 1
minute (+/- 2 seconds) for the EA reset condition to be met. If this
does not occur the vend is assumed to have failed and is dealt with
in the same way as for blocker hold reset.

EXTERNAL CREDIT DISPLAY
For electro-mechanical interface applications the external display, if
fitted, can provide the following information:
• Current credit in real money (Consumer)
• Vend price in real money, used in price display
mode(Consumer)
• Accumulated credit in price teach & float modes
(Operator / Route person)
• Power-on indicator (Service engineer)
• Value of cash in tubes (Operator / Route Person)
DISPLAYING CREDIT
If there is credit in the system, either coin or value token, then the
total value of this credit will be displayed. The display will be in real
money units. Any leading zeros will be blanked. The decimal point
will be lit according to the decimal point setting in the EEPROM. A
decimal point setting of 0 indicates zero places of decimal, i.e. the
decimal point is lit on the right hand digit. A decimal point setting of
1 indicates one place of decimal, and so on. Any value of decimal
point over 4 will be ignored and no decimal point will be lit.
If there is free vend credit available, either by free vend token or host
machine free vend, the credit display will indicate this by a display
of 5 dashes on the middle segments.
If there is no credit in the system, the display will show a single 0 in
the right hand digit. No decimal point will be lit.
CANCELLING CREDIT
If you have been testing or resetting the changegiver outside of a
shifted mode you may accumulate credit in real money terms. To
cancel any credit, press the mode key once followed by the A key
twice.
Page 40
34©, MEI., 1996.
CashFlow 560 changegiver Applications Design Guide
DISPLAYING VEND PRICE
If price display is enabled, and you make a selection whose value is
less than the current system credit, then the display will show the
price of the vend, in real money, while the selection is active.
Leading zero blanking and decimal point will be handled as the
display of credit.
DISPLAYING PRICE TEACH CREDIT
If the changegiver is in price teach mode, the current value of credit
will be displayed in real money values. Leading zero blanking and
the flashing decimal point will be handled as the display of credit.
DISPLAYING FLOAT VALUE
If the changegiver is in automatic float mode, the total value of any
coins accepted as float will be displayed in real money values.
Leading zero blanking and the flashing decimal point will be handled
as the display of credit. This value is removed when the changegiver
returns to normal operation.
POWER ON INDICATOR
On system power-up or reset, the changegiver will light all segments
of the display for 0.5 seconds. If there is no host or changegiver fault
present, the red LED will light. This will provide you with a basic
check of the display and associated H/W.
DISPLAYING TUBE VALUE
A display of the value of coins the changegiver thinks are contained
in the tubes can be obtained by pressing the mode key twice with
the tube cassette fitted. The tube contents value will be displayed for
2 seconds on the display.
Note that the calculation is based on tube counts, and on the value
of the first coin type in the tube.

MAN MACHINE INTERFACES
KEYPAD
All changegivers have a keypad mounted on the front face. Two
LEDs are also mounted in this area to indicate the operational state
of the changegiver. The keypad will enable the following functions
to be performed:
• Dispense coins
• Set price(s). See Note below.
• Float the changegiver
• Reset tube counts
• Home the dispensers
• Display the value of coins in the tubes
NOTE: Setting Prices is available at all times with electromechanical product, unless Route Alpha terminal address
245 has been set to inhibit.
With BDV and Executive product it will apply only when
Route Alpha 250 terminal address 238 has been activated.
Setting Prices function is not available for MDB product.
The keypad has four letter keys and a mode key. The mode key
allows shifted functions to be associated with each of the letter keys.
Two LEDs provide simple diagnostic information and will assist the
use of the keypad. The diagram below shows the layout of the
keypad and its associated labeling. The following sections describe
its operation.

LED Usage
The top (yellow) LED is used to indicate whether the keypad is in
normal or shifted mode. If the LED is off, the keypad mode is in
normal mode. When the mode key is pressed, the yellow LED will
start to flash at 2 Hz (± 1%) to indicate that the shifted functions
defined by the icons on the keys, are accessible. Note that the mode
key does not need to be held down to access the shifted functions.
If no further key is pressed within 10 seconds, or the mode key is
pressed a second time, the keypad will return to its normal mode.
The yellow LED will go off, and the shifted functions will be disabled.
If a letter key is pressed within 10 seconds, then the changegiver will
turn the yellow LED on continually, and attempt to perform the
required action. See the following sections for details of the shifted
functions.
The bottom (red) LED is used to indicate the fault status of the
system. If there are no errors, the LED will be illuminated
continually. If a changegiver error is detected, then the red LED will
flash at 2Hz (± 1%). If a fault is detected on the host machine, then
the red LED will be turned off. Machine faults will take precedence
over changegiver faults.
If the state of the system requires that both LEDs flash, then they will
be synchronized to each other in anti-phase (i.e. yellow on - red off,
yellow off - red on).
Manual Coin Dispense
If the changegiver is idle (i.e. not vending or accepting coins), the
user can manually dispense coins from the 4 tubes by simply
pressing the relevant letter key. On a single press-and-release of a
letter key, the changegiver will attempt to pay a single coin from the
requested tube.
If you wish to get more than 1 coin from the tube, you can continue
to hold the key down. This will cause the changegiver to start
dispensing further coins at the rate of 1 coin every 0.5 seconds
(subject to the dispenser cycle time being less than this).
If you release the key within 3 seconds of the initial press, then
dispensing will stop after the current coin is dispensed. Multiple
dispensing is not allowed on empty tubes (tube counts = 0).
If the key is held for more than 3 seconds, dispensing will latch, and
release of the key will have no effect. The dispenser will continue to
dispense a coin every 0.3 seconds (subject to the dispenser cycle
Page 44
38©, MEI., 1996.
CashFlow 560 changegiver Applications Design Guide
time being less than this) until the tube counts reach their
programmed safe count, or any key is pressed.
If 2, or more, letter keys are pressed at the same time, then the
changegiver will pay coins from the selected tubes in the same
manner as described above. Note that the 3 second latch time is
measured from the time the last key is pressed, and dispensing will
not unlatch until all the selected tubes reach their programmed safe
count.
Automatic Tube Float (Float Up)
You can refill the tubes to their pre-programmed float level by the
use of the float function. Float is only available if the changegiver is
idle. To access float, press the mode key to get the shifted functions,
and then press the key with the float icon (key A). Entering float
mode will clear any accumulated credit, and will be indicated on the
changegiver’s credit display by all decimal points being lit.
On entry to float, a longer time-out of 45 seconds will be started. You
can then enter coins via the acceptor. The changegiver will
automatically accept only the coins required to bring the tubes up to
their programmed float level. On a tube reaching the required float
level, any further coins of that type will be rejected. The value of any
coins accepted as float will be accumulated, and displayed on the
credit display (if fitted). This display value will be shown with the
decimal point flashing.
During float the yellow LED will remain on, indicating that a shifted
function is active. The changegiver will exit float mode, and turn off
the yellow LED, if any of the following occur:
• No float coins accepted during a 45 second period
• The float key (A) is pressed
• The float down (C) key is pressed
• The reset tube counts key is pressed
Note that on exit of float, there is no need to press the mode key first,
as the shifted functions are already active. When float mode is
exited the changegiver will clear down the credit display, and
resume normal coin acceptance.
If float mode is exited by either of the first two methods above, then
the tube counts will not be modified further. If float mode is exit by
pressing the reset tube counts key, then the tube counts will all be
set to their pre-programmed float levels.
Page 45
©, MEI., 1996.39
CashFlow 560 changegiver Applications Design Guide
Float Down Mode
When you wish to float down the tubes, simply press the mode key
to get to the shifted functions, then press the A key to enter float
mode, followed by the C key. At this point the changegiver will start
to dispense coins until all tube counts reach the pre-programmed
float levels. Note that if all counts were equal to or less than the float
levels, then no dispense will occur.
Resetting Tube Counts
You can force the tube counts to be set to their pre-programmed
values by use of the reset tube counts function. In order to avoid
inadvertent resetting of tube counts, this function is only enabled if
the changegiver is in float mode, and an IDTS audit FEM is not
present.
If key B is pressed while the changegiver is in float mode, then all of
the tube counts for the 4 main tubes will be set to their preprogrammed float levels. The changegiver will then exit float mode.
If the actual number of coins in the tubes do not match these float
levels, then the coin counts will be incorrect until recalibration
occurs. If access to this function is attempted when the changegiver
is not in float mode, i.e. pressing the mode key, then pressing the
reset key, it will be ignored. The keypad will revert back to normal
mode after 10 seconds and the yellow LED will then stop flashing.
Price Teach
Subject to the earlier note the prices held by the changegiver can be
set using the price teach function. Price teach is only available if the
changegiver is idle. To access price teach, press the mode key to
get the shifted functions, then press the key with the price icon (key
C). Entering price teach mode will clear any accumulated credit, and
allow the user to clear credit, and will be indicated on the
changegiver’s credit display by all decimal points being lit.
On entry to price teach, a longer time-out of 45 seconds will
commence. You can then enter coins via the acceptor to the value
required for the price to be set. Any coins entered will be
accumulated as credit, and displayed on the credit display, if fitted.
This display value will be shown with the decimal point flashing.
If there is accumulated credit, then any selection which becomes
active will have its price set to the value of credit accumulated. If no
credit was accumulated, then any selections made will not have
their price modified. This is to prevent inadvertent zeroing of prices
on permanent sense machines. Price teach only allows the setting
of non-zero prices. Should you wish to clear a price to zero, then the
Route Alpha 250 terminal must be used.
Page 46
40©, MEI., 1996.
CashFlow 560 changegiver Applications Design Guide
The sequence of inserting coins then making a selection can be
repeated for all selections for which you wish to modify the price.
Note that the main principle of price teach is that selections will have
their price set to the current accumulated credit value, so that if a
number of selections are required to be set to the same price, once
the correct credit value is reached, all that needs to be done is to
press the selection buttons.
During price teach the yellow LED will remain on, indicating that a
shifted function is active. In addition, all keys except the price teach
key will be ignored. The changegiver will exit price teach mode, and
turn off the LED, if any of the following occur:
• No activity relating to price teach made during a 45
second period.
• The price teach key is pressed.
Note that on exiting price teach, there is no need to press the mode
key first, as the shifted functions are already active. When price
teach mode is exited the changegiver will attempt to return any
accumulated credit to the user using the tube coins.
Note that on serial interface changegivers, the prices are not
normally held in the changegiver and are thus inaccessible to this
form of update, unless the price holding option is enabled via the
support terminal.
Homing the Dispensers
You can home all the dispenser arms by first pressing the mode key
to get the shifted functions, then pressing the mode key a second
time. This will home each of the dispenser arms which are not seen
to be at home, as read by the position sensors. This will only work if
the tube cassette is removed.
Displaying Tube Value
You can easily get a display of the value of coins the changegiver
thinks are contained in the tubes by pressing the mode key twice
with the tube cassette fitted. This will cause the tube contents value
to be displayed for 2 seconds on the changegiver’s credit display.
Note that only tubes which are set up as fitted will be included in this
calculation. Note also the calculation is based on tube counts and
on the value of the first coin type in the tube.

INTERNAL DIAGNOSTICS & ERROR HANDLING
The indication of an error being present either in the host or in the
changegiver is given by the red LED. This section details various
errors, and the action taken by the changegiver.
• Host machine problems
• Coin handling problems
• On-board EEPROM problems
• Audit FEM problems
• FIB communication errors
• Miscellaneous errors
HOST MACHINE PROBLEMS
Host Inhibited
On both electro-mechanical and electronic hosts, an indication is
provided to the changegiver if the host is inhibited (e.g. blocker
inactive on electro-mechanical machines, no polling on MDB). The
error handling for this condition is:
• Indicate host error on LED
• Disable all coin acceptance in normal mode
• Disable all coin acceptance in float mode
• Disable all coin acceptance in price teach mode
• Manual dispense is still allowed
• Route Alpha 250 terminal comms still allowed
• Changegiver will continually check if host is re-enabled
Removal of Blocker
The start of vend condition on electro-mechanical hosts is signalled
by blocker becoming inactive after the price relay has been turned
on. Normally there is a 2.5 second timeout on this, which will
terminate the vend sequence with no loss of credit should blocker
not go inactive. In blocker hold mode, due to the possibility of
frauding certain machines, this timeout is not used. Therefore, if the
start of the vend (as signalled by the removal of the blocker signal)
does not occur, the following error state will result:
• Indicate host error on LED
• Inhibit all changegiver functions
• Changegiver will continually check if vend starts
Page 48
42©, MEI., 1996.
CashFlow 560 changegiver Applications Design Guide
Blocker Return
The end of vend condition on electro-mechanical hosts depends on
the reset mode selected. In blocker hold mode, the end of vend is
signalled by the return of the blocker signal. If this does not occur,
the following error state will result:
• Indicate host error on LED
• Inhibit all changegiver functions
• Changegiver will continually check if host is re-enabled
Cashbox Full
An input is provided for a cashbox full sensor (provided by the host).
The error handling for this sensor is:
• Indicate host error on LED
• Set cashbox full error flag (code 7 in error register)
• Disable all coin acceptance in normal mode
• Disable all coin acceptance in float mode
• Disable all coin acceptance in price teach mode
• Manual dispense is still allowed
• Terminal comms is still allowed
• Cashbox must be emptied to reset error

ON-BOARD EEPROM PROBLEMS
Incorrect Configuration vsn. No.
If the configuration file version number in the on-board EEPROM
does not match the version expected in the software, the following
error handling applies:
• Set code 4 of EEPROM error register
• Indicate changegiver error on LED
• No upload of EEPROM data will occur
• All coin acceptance will be disabled
• The keypad will be disabled, apart from the mode key
• Terminal comms. still allowed
• No save of data to EEPROM on power fail
Page 51
©, MEI., 1996.45
CashFlow 560 changegiver Applications Design Guide
• The configuration version number must be corrected.
The error will then be cleared on changegiver reinitialisation. This can be done by;
• Clearing the error flag,
• Updating the EEPROM version number,
• Re-initialising.
EEPROM Corruption
If a corruption is detected in the EEPROM at upload time, the
following error handling applies:
• Set code 0 - 1 of EEPROM error register
• Indicate changegiver error on LED
• No upload of EEPROM data will occur
• All coin acceptance will be disabled
• The keypad will be disabled, apart from the mode key
• Terminal comms is still allowed
• No save of data to EEPROM on power fail
While a reset device error appears to clear the error, note that there
will be no configuration data uploaded into RAM, and hence the
changegiver’s operation will be indeterminate. After clearing the
error, the checksum of the affected page should be corrected and
the changegiver re-initialised.
Write Timeout
If a timeout occurs when writing to theEEPROM, the following error
handling applies:
• Set bit 7 of EEPROM error register
• Indicate changegiver error on LED
• All coin acceptance will be disabled
• The keypad will remain enabled, with manual dispense
still allowed
• Terminal comms is still allowed
• No save of data to EEPROM on power fail
• Changegiver must be switched off to reset error.
Page 52

AUDIT FEM PROBLEMS
Audit not initialised
If a FEM is present but has not be initialised, the following applies:
• Set code 5 in error register
• Indicate changegiver error on LED
• No coin in / out events will be audited
• Vending is disabled
• Audit must be initialised to clear error.
Audit FEM corrupt
If a FEM is present but is corrupt, the following applies:
• Set code 2 in error register
• Indicate changegiver error on LED
• Suspend all changegiver operation apart from FIB
comms
• Mode key still operates
• Corruption may self repair if power is cycled. If not,
then FEM must be replaced.
Audit removed
If a FEM had been present but is now removed, the following
applies:
• Set code 3 in register
• Indicate changegiver error on LED
• Suspend all changegiver operation apart from FIB
comms
• Mode key still operates
Audit must be re-fitted and changegiver re-initialised to clear error.
HOST INTELLIGENT INTERFACE(HI
2
) ERRORS
The HI
2
is the internal comms highway that handles all messages
between the acceptor and the control board
HI2 Error
If an error occurs in the HI
2
protocol stack the following error
handling applies:
• Indicate changegiver error on LED
Page 53
©, MEI., 1996.47
CashFlow 560 changegiver Applications Design Guide
• Set codes 2 / 3 in error register
• Will not allow the changegiver to enter float or teach
modes.
• Coin acceptance inhibited
• Manual dispense is not allowed
• Terminal comms is still allowed (if access is permitted)
• Changegiver will continually check if failure rectified
MISCELLANEOUS ERRORS
Acceptor Initialising Error
If there is a failure to transfer over data between the acceptor and
control board on power-up, the following error handling applies:
• Indicate changegiver error on LED
• Set code 1 in error register
• All coin acceptance will be disabled
• Manual dispense is still allowed
• Terminal comms is still allowed
While a reset device error appears to clear the error, note that the
data for coin routing, inhibits, coin types, etc. may not have been
correctly passed between the acceptor and the changegiver, and
hence the changegiver’s operation will be indeterminate. After
clearing the cause of the error the changegiver should be reinitialised.

VIA MEI
ROUTE ALPHA 250 TERMINAL
With a MEI Route Alpha 250 terminal you can re-configure any of
the functions available for a particular product. The terminal is
connected to the acceptor via a six way connector which plugs into
the front of the acceptor.
The terminal is used to check or change certain data which affects
the way the changegiver operates. The data is held in addresses.
Each address has a unique number which identifies the feature you
wish to read or change e.g. if you want to change from single vend
to multi vend then you need to go to address number 226 and put in
a 1 (single vend is a 0).
The following pages will explain how to access and change the data
in certain addresses. At the end of this section there is a list of
addresses and the relevant values. Particular reference should be
made to the symbols in this section which indicate the applications
(i.e. electromechanical, Executive, BDV and MDB) for which each
address is appropriate.

CashFlow 560 changegiver Applications Design Guide
KEY FUNCTIONS
Reset Key: used to reset all modes and to initialise any settings that
you have changed. If the reset key is pressed while an address is
being updated then the address may not be updated. The reset key
must be pressed to store the changes that you have made.
Up Key: used to increase the value displayed on the screen.
Down Key: used to decrease the value displayed on the screen.
Left Key: used to scroll the display to the left when a large number
is being accessed that cannot be fully displayed on the screen.
Right Key: used to scroll the display to the right when a large
number is being accessed that cannot be fully displayed on the
screen.
Enter Key: used to change between the address and data displays.
Other Facilities of the Terminal
The terminal has several features to speed up its use. This includes
the ability to scan at a higher speed with the keys auto repeating, to
automatically roll over from its highest to lowest address and to
inform the operator should a communication error occur.
Should you need to know which version numbers of the software is
used in the changegiver the UP key is pressed while the terminal is
in reset mode. The terminal will firstly display the acceptor HI
2
node
address, if the UP key is pressed again the acceptor software
version number will be displayed. Pressing the UP key again will
display the acceptor eeprom number and if pressed again the
acceptor configuration code. Pressing the RIGHT key will display
the changegiver’s software number
To return to normal operation press the RESET key.

Auto Repeating Keys
If either the UP or DOWN keys are kept pressed they automatically
repeat. The repeat speed of the key increases the longer the key is
held down.
Double Click Hotkeying
If a key is doubled clicked (pressed twice in quick succession) then
this causes the address number to increment by a larger amount.
e.g. if the user starts at address number 1 then double clicks the UP
key, the address will jump to 40, double click again the address will
jump to address 100 etc. This is useful as the addresses used for
the changegiver start at address 200. You can also double click the
DOWN key to decrement by larger amounts.
USING THE TERMINAL
As soon as the terminal is connected to a changegiver it powers up
and interrogates the product.
The terminal display will clear and briefly show a message that
indicates the version of software in the terminal. A display of [0 1.0]
means software with a version number of 1.0 is fitted in the terminal.
After a few seconds the display will show the number [1.] or [1.-]. Not
all configuration items are applicable to every product but all the
address values are shown on the display. If the value for the
address is applicable to the product a dash will be present at the far
right position on the display. The value can then be accessed and
changed if required.
Power up message Software version = 1.0
No dash displayed
Address is not accessible
for this product
Dash is displayed Address

Page 57
©, MEI., 1996.51
CashFlow 560 changegiver Applications Design Guide
The basic operation to alter the information held in an address is:
1 Connect the terminal to the CashFlow
product.
2 Wait for the terminal to power up correctly.
3 Select the address by using the UP and DOWN keys.
4 Examine the data by pressing the ENTER key.
5 Alter the data value by pressing the UP or DOWN keys
until the new value has been reached.
6 Press the ENTER key to return to displaying addresses.
7 Press the RESET key to initialise the new value.
When the terminal is displaying values stored at addresses, no
decimal point will be displayed.
If an error occurs with the communication between the terminal and
the changegiver the display will show an error message of four half
height zeroes.
This message will stay on the display. Pressing the RESET key may
clear the fault. The display will then revert to showing the current
address. If the error occurred while updating an address then the
value of that address should be checked as it may not have been
updated correctly. If, after pressing the RESET key, the fault
remains the error message will stay and you need to return the
terminal for repair.
As the screen is capable of only displaying four digits at any one
time the number displayed on the screen can be scrolled if it is
greater than 9999 by using the LEFT and RIGHT keys. The left or
rightmost digit will flash indicating an extra digit can be examined by
use of the scrolling keys e.g. Value is 12345

VISUAL AUDIT
Visual Audit can be obtained, from the electro-mechanical and
Executive products only, when an audit function expansion module
(FEM) is installed as an accessory on to the Control PCB.
Data can be viewed with the use of a Route Alpha 250 terminal and
the process for using this method follows below. Data is also
available via a MEI
®
hand-held printer which can be accessed
through an interface loom from the changegiver, through a DEX/
UCS jack-plug connected to a MEI
®
MEQ terminal, or from an infrared optical interrogation point in the side of the machine, also using
the MEQ terminal.
Visual Audit Interrogation
The Route Alpha 250 terminal display may not be able to show all
details for each address. In order to ensure that all data has been
read two quite separate addresses must be interrogated, one
consisting of the least significant (ls) digits, and the other the most
significant (ms) digits of the data.
To convert these two readings to a single audit value the (ms) value
shown must be multiplied by 65536 and the (ls) figure added to the
result.

The following process should be followed to use the Route Alpha
250 terminal for retrieval of data:
• Firstly select the required address using the Up and
DOWN keys.
• Press ENTER to display the contents of the address. If
the value exceeds four digits the LEFT and RIGHT
keys are used to scroll the display left or right.
EXAMPLE. (To read the Cash In Tubes value)
• Select address 900
• Press ENTER to display the (ls) value, (e.g 54919)
• Press ENTER to return to address mode
• Press UP to select address 901
• Press ENTER to display the (ms) value, (e.g. 18)
• Multiply (ms) value by 65536 (18 x 65536 = 1179648)
and add (ls) value. (1179648 + 54919 = 1234567)
NOTES
All values are displayed on the terminal with no decimal point.
In order to reset the interim values address 999 must be used,
ensuring that it is set to 9.
All values displayed will be in the range of 0 - 65535.
The relevant addresses for the Route Aplha 250 terminal in the
following list are 900-999.

CashFlow 560 changegiver Applications Design Guide
Testing the Terminal
It is possible to test all the features of the terminal itself by putting
the unit into a special test mode. To enter the test mode hold the
ENTER key pressed when powering the unit up. The display will
initially show three digits indicating the result of an automatic on
board test. The display format is:
[<BUSY state> <DATA state> <AUTO TEST result>] where
<BUSY state> = current state of BUSY line, 0 = low, 1 = high
<DATA state> = current state of DATA line, 0 =low, 1=high
<AUTO TEST result> = result of automatic test
0 = Pass
1 = BUSY line error
2 = DATA line error
3 = BUSY and DATA line errors
Pressing the ENTER key activates the next stage of test.
The LCD is tested by displaying a pattern of four identical digits on
the display. The digits alter every 1/2 second and the display should
be examined to check all the digits are formed correctly.
Display will show:
[0000], [1111], [2222], [3333], [4444], [5555], [6666], [7777], [8888],
[9999], [----], [oooo], [ ], [....].
Pressing the ENTER key activates the next stage of test.
The terminal keys are checked next. A single number is shown on
the display indicating what key was pressed last. Display shows:
[ 0] No key pressed
[ 1] UP key pressed
[ 2] RIGHT pressed
[ 3] DOWN key pressed
[ 4] LEFT key pressed
[ 5] ENTER key pressed
This is the last test and the RESET key must be pressed to restart
the terminal in normal operational mode.

ENVIRONMENTAL PERFORMANCE
Products are available to meet the following environmental
specification.
TEMPERATURE RANGE
Working ambient - 15 to 60°C
Max rate of change 15°C/hr non condensing
Storage -40 to + 65°C
Solar radiation Max. working ambient applies
HUMIDITY
Operational Worst case up to 90% RH, non condensing
at 43°C
Storage Worst case up to 95% RH, non condensing
at 65°C
VIBRATION
Operational - units will not be damaged by these conditions:
INSTALLATION
To ensure that the changegiver operates correctly it must be
mounted so that it hangs within
+2° of vertical from both front and
side elevations.
The reject lever must have a minimum 3mm clearance from the
machine reject mechanism when installed.
The amount of travel for the coin mechanism’s reject lever when
engaged should normally be between 12-18mm. It should not be
forced beyond this point as there is a danger of the reject lever
bottoming out and damage being caused.
Vibration (through machine
mounting)
0.25g at 5 to 500 Hz.
Intermittent over the unit’s
life. Refer to BS2011: part
2.1 Fc:1983
Page 73
©, MEI., 1996.67
CashFlow 560 changegiver Applications Design Guide
TRANSPORTATION
Units in the packed state will not sustain any physical damage under
these conditions:
Shock Half sine, 30g shock, 18ms dur . Refer to BS
2011: part 2.1 Ea: 1977
Bump 1000 bumps 6ms duration at 25g. Refer to
BS 2011: part 2.1 Eb: 1977
Free Fall 1000mm fall onto packing faces. Refer to
BS 2011: part 2.I Ed: 1977
Crush Neatly stacked units of the same type may
be stacked to a height of 2 metres.
LIQUIDS
Water
The units inclusive of PCBs will be splash protected.
The coin entry encourages excess water towards the reject path
and the front of the product out of the coin path. Coin stall under
these conditions is minimised.
The above should in no way be interpreted as a specification
capable of operating at 100% RH.
Salt Water
As above.
Prolonged exposure in a salt laden atmosphere will lead to PCB
corrosion damage.
Other Liquids
This includes: dilute carbonic acid, dilute citric acid, carbonated
drinks, beer, tea, coffee, chocolate, soup, syrup, sugar residue and
uric acid.
• Certain beverages and the dilute acids may cause similar effects to salt water if they contact the PCB’s.
• Wet performance will be similar to that described for
water.
• Liquids which leave a residue on drying which affects
the passage of coins could cause malfunction.

CashFlow 560 changegiver Applications Design Guide
VOLTAGE
Supply
The unit will operate to specification on the following supply
voltages:
46 - 64 Hz AC RMS.
• 20.4 - 26.4 V RMS
• 87 - 121 V RMS
• 95 - 132 V RMS
• 187 - 242 V RMS
• 212 - 264 V RMS
• 207 - 244 V RMS* single transformer profile
Note: For each of the above voltage waveforms the peak voltage
must be √2 V RMS
DC (BDV)
Absolute maximum voltage - 40 volts DC. Minimum voltage - 22
volts average DC (with up to 7 volts peak to
peak ripple 94 -126 Hz.)
DC (MDB)
Absolute maximum voltage - 44 volts DC (Typically 34 volts)
Minimum voltage - 18.5 volts average DC (with up to 7 volts peak to
peak ripple 94 -126 Hz.)
NOTE. During the life of the defined products, there will be a
requirement for European equipment (whole vending machine) to
operate at 230 V +6%, -10%. Most countries except UK have
agreed to this change. The 240V transformer design is such that this
change can be accommodated.
VOLTAGE TRANSIENTS
Minimum performance can be regarded as that stated under the
section on susceptibility.
The unit will perform to criteria A for supply loss (100%) of up to two
cycles.
For supply loss of greater than 2 cycles then performance criteria B
applies.
For DC (BDV / MDB) units, voltage transients that go below the
minimum average level - peak ripple voltage, will cause variance to
performance criteria B. (i.e. loss of credit).

changegiver product
• Robust Terminal cable
• Bill validator cable/s to host power
• Bill validator interface
• BVI to bill validator cable
•MEI

CashFlow 560 changegiver Applications Design Guide
The successful connection of the changegiver and the bill validator
has two phases, that of installing the Robust Terminal cable into the
changegiver, and the connection of that cable to the bill validator.
To install the Robust Terminal cable into the changegiver the
following process must be followed, having first dis-connected the
CashFlow
®
product’s power plug:
The next step requires the use of the correct interface cable, the part
numbers of which are shown in the following table
a) Remove the coin storage cassette from
the front of the product by squeezing the
blue tabs in the centre of the cassette.
b) Release the acceptor module and tilt
forward by pressing the blue retaining
catch down with a fine screwdriver at
point A.
c) Dis-engage the cable restraint at point
B by gently pulling the side of the channel outwards. Remove the right-most
grommet. Connect the 6-pin end of the
Robust Terminal cable into CON 16 on
the control board, located at point C.
d) Feed the cable towards the point where
the grommet was removed, ensuring
that it lays flat and is behind the cable
retainer at point D. Insert the cable
grommet and re-engage the cable
restraint.
Replace the acceptor module and coin
storage cassette.

To connect the bill validator to the changegiver:
a)Ensure that the required interface cable is available,
confirming this with the table on the previous page. Each
cable should have its part number on a label attached to it.
b)Connect the Robust Terminal cable to the 10-pin socket on
the left hand side of the BVI (label side up). At no time
should the MEI
®
Route Alpha 250 terminal connector be
attached to this socket.
c)Connect the interface cable to the 34-pin socket on the right
hand side of the BVI. The other ends of the cable attach to
the bill validator and host power socket. At the bill validator
end of this cable secure the black screen (with solder tag)
to a bill validator mounting bolt.
d)Where the bill validator and the changegiver have different
supply voltages you are advised to consult with your MEI
regional office technical support team for advice regarding
changegiver loom options.
e)Apply power from the host machine and set up the system,
through the changegiver, using the MEI
®
Route Alpha 250
terminal. Reference should be made to the terminal
address data on the BVI label.
An explanation of the symbols shown on the BVI label is
given on the next page.
f) Set the changegiver to maximum credit enabling the
highest value bill to be accepted (using Route Alpha 250
terminal address 200). Ensure that there is sufficient
change in the tubes to enable bill acceptance.
g) Ensure that all of the bill validator switches are correctly set.
NOTE: When installing a GL2C type bill validator any enable
switches MUST be set to OFF.
